BOTTLE-SEALING DEVICE.

SPECIFICATION forming part of Letters Patent No. 590,578, datedSeptember 28, 1897.

Application filed January 27 1897. Serial No. 620,873 (No model.)

To all ZUhOTIb [It TIMI/7 (to/warn.-

Be it known that I, LEWIS KALLING, of the city of Baltimore, in theState of Maryland, have invented certain Improvements in Bottle-SealingDevices, of which the following is a specification.

This invention consists, first, in the formation of a joint between thebottlehead and the sealing-cap by means of a compressible gasket, whichis so drawn and flattened as to present only a feather or knife edge toany liquid that may pass over the bottle-lip or between the lip and theinner surface ofthe cap, with which the said lip is practically incontact. By this means rubber or any other substance which is welladapted as a jointforniing material may be used without danger of itscontaminating or inj uriously affecting the contents of the bottle, aswill hereinafter fully appear.

The said invention consists, secondly, in the combination,with a bottlehaving a lip with an inclined, beveled, or rounded exterior surface, ofa flexible sealing-cap of such shape that when it is brought in contactwith the upper end or edge of the bottle-lip it will stand away from thesaid inclined, beveled, or rounded surface and thereby form a space foran annular compressible gasket, as hereinafter more particularlydescribed.

In the further description of the said invention which follows referenceis made to the accompanying drawings, forming a part hereof, and inwhich Figure 1 is a vertical section of the upper part of a bottle and asealing-cap of the character shown and described in Letters Patent No.468,226, granted on the 2d day of February, 1892, to Villiam Painter,for bottle-sealing devices, the same being provided with a joint-forminggasket in accordance with the present invention and illustrating theposition of the gasket before the same is compressed. Fig. 2 is a viewsimilar to Fig. 1, except that the cap and gasket are shown in thepositions which they occupy after the joint is formed. Fig. 3 is a topview of the cap. Figs. 4c, 5, and 6 show the invention as applied to thesealing device patented to George A. Boyden March 6, 1894, under No.515,990. Figs. 7, 8, and 9 illustrate the application of the presentinvention to the bottle-sealin g device patented to me on the 9th day ofJune, 1896, and numbered 561,792. In the Painter patent referred to theflange portion of the sealing-cap A is corrugated, the corrugationsbeing divided into classes, termed in the specification the inner andthe outer on es,and the cap is secured to the bottle by forcing theinner corrugations under a shoulder formed on the bottle-neck.

Instead of the sealing-disk shown in the Painter patent- Iplace withinthe cap, which does not fit the outer surface of the bottle-lip,immediately below its extreme end, an annular gasket CL of somecompressible substance, preferably rubber, which has an inner diametergreater than that of the upper edge of the lip of the bottle. Thisgasket, as the cap is forced down and its inner surfacce brought intocontact With the extreme upper edge of the bottle-lip, is confined inaspace between the cap and the surface I) of the bottle-lip formed by thedifference in configuration of cheapens the sealing device withoutdetract- 7 ing in any manner from its eificiency. It will be seen thatthe lower end of the gasket is also feather or knife edged; but this isonly incidental to the shape of the shoulder and the cap, and the resultwill be the same if the thickness of the gasket at the center becontinued to the bottom, as it is not in contact with the liquid in thebottle. From the foregoing it will be understood that the distinguishingfeature of this joint is the contact of the cap with the bottle and thedrawing of the gasket so as to produce a knife-edge at its upper end,which is on the exterior rounded or beveled surface of the bottle-lip.

XVhile I have stated that the inner surface of the cap is in contactwith the extreme end of the bottle-lip, I do not debar myself fromcoating the inner surface of the cap with some innocuous varnish madefrom paraffin or some suitable resinous substance to prevent thecontents of the bottle coming into contact with the metal of the cap,the intention of the invention being to dispense with a disk or gasketwhich is inserted in the cap to form a joint between its inner surfaceand the extreme end of the bottle-lip.

The employment of a disk between the upper edge of the bottle and thecap would in the compressing operation to which the gasket is subjectedcause a portion of the same to enter to some extent the throat of thebottle and bring it into contact with the liquid therein, a result whichwith my invention is entirely obviated.

The Boyden cap shown in Figs. 4, 5, and 6 is held to the bottle-head byfriction alone, the head of the bottle being ground to give it accuracyin diameter and a true surface, over which the cap is drawn in thejointforming operation.

The gasket a is applied to the Boyden cap in the same manner as to thePainter cap and presents a knife-edge to anyliquid which may pass overthe bottle-lip.

To adapt the gasket to my patented cap, which is shown in Figs. 7, 8,and 9, the gasket is made somewhat wider than the hollow bead in thecap, as shown in Fig. 7, so that in the compressing operation a portionof the gasket will pass upward toward the end of the lip of the bottleand terminate in a knifeedge, as shown in Fig. 8.

By reference to the drawings it will be seen that in all cases thecurvature or configuration of the innersurface of the sealingcap differsfrom that of the outer surface of the bottle-lip immediately below theextreme end thereof, so that a space is left for an annular gasket.

I have illustrated the application of myinvention to three distinctivetypes of sealin caps, but it is evident that it is applicable to others,provided the cap is made to stand away from the inclined, beveled, orrounded outer surface of the bottle-lip, so as to givespace for anannular gasket, which is compressed in thesaid space.

I claim as my invention- A bottle having a lip with an inclined,-beveledor rounded exterior surface, and a flexible sealing-cap the annular wallof which immediately below the crown thereof has an inclination, bevelor curvature different from that of the exterior of the lip of thebottle so as to form an annular space immediately below the upper edgeof the lip, but which annular wall at its lower edge is in contact withand clamps the bottle-head, combined with an annular compressible gasketwhich is inclosed within and entirely fills the said space,substantially as specified.
